Example: Suppose you have a SIP proxy server connected to the DMZ zone for
VoIP calls. You could configure a firewall rule to allow VoIP sessions from the SIP
proxy server on DMZ to the LAN so VoIP users on the LAN can receive calls.
Create a VoIP service object for UDP port 5060 traffic (Configuration > Object >
1
Service).
Create an address object for the VoIP server (Configuration > Object >
2
Address).
Click Configuration > Firewall to go to the firewall configuration.
3
Select from the DMZ zone to the LAN1 zone, and add a firewall rule using the
4
items you have configured.
• You don't need to specify the schedule or the user.
• In the Source field, select the address object of the VoIP server.
• You don't need to specify the destination address.
• Leave the Access field set to Allow and the Log field set to No.
Note: The ZyWALL checks the firewall rules in order. Make sure each rule is in the
correct place in the sequence.
